Application March 20, 1935, Serial No. 11,933

3 Claims.

This invention relates to window screens and more particularly to such ascreen arranged to be rolled up upon a spring roller in a manner similarto that of a window curtain, and an object of the invention is toprovide a simple construction which is cheap to manufacture and simpleto install. A further object is to provide simple guide and holdingmeans for the edges of the screen fabric to prevent kinking and bucklingand to facilitate manipulation. It is also an object to so mount thewinding roll as to guide the screen fabric into and out of its guidewaysand prevent kinking or sharp bending of the fabric where it leaves theguides and at the same time provides for the enlargement of the roll ofscreen fabric as the screen is wound upon the winding roll.

- The invention further consists in certain other new and usefulfeatures in the construction, arrangement and combination of elements,all as hereinafter more fully set forth, reference being had to theaccompanying drawing, wherein:-

Fig. 1 is a front side elevation of a screen as applied in use andembodying the present invention and showing parts of the structurebroken away and in section to more fully disclose the construction;

Fig. 2 is a vertical section substantially upon the line 2-2 of Fig. 1;

Fig. 3 is an enlarged sectional detail;

Fig. 4 is a detail showing a modified construction of screen-edgeclamping means showing the same in elevation; and

Fig. 5 is a vertical section substantially upon the line 5-5 of Fig. 4.

- As shown in the drawing I indicates the usual window frame having theusual vertical side guides 2 for an upper sash 3 and a lower sash 4, theframe having the usual sill 5. Secured to the side members of the frameI outside the guides 2 for the lower sash, are channel members 6, eachformed of sheet metal and of U-shape in cross-section to receive thesideedges of a screen fabric 1 of a length to extend from the upper endof the window frame to the sill 5 to which sill is secured a U-shapedmember 8 similar to the side channel member 6 and secured with its endsin alignment with said channels to form a continuation thereof acrossthe sill with the channel .of this member 8 open upwardly to receive abinding strip 9' of sheet metal secured in any suitable manner to thelower end edge of the fabric screen I, the guide channel members 6 andbottom channel 8 being secured in place by screws H! (see Fig. 3)passing through openings in the bottom wall of each channel and into thewood frame and sill with the heads of these screws within the channels.By this means the channel mem: bers may be quickly, easily andaccurately secured in place with the heads of the securing screwsconcealed from view within the channels.

The upper end of this screen fabric is secured in any suitable manner toatransverse roller ll mounted within a suitable casing l2 secured to theupper end of the window frame I and extending completely across theopening of said frame at its upper end, this casing comprising end wallsl3, an inner side wall l4, and a semi-circular outer side wall IS withthe lower side edge of this outer wall, extending across adjacent theouter side of said screen and abutting the outer sides of the guidechannels 6 at its ends, thus providing an opening or slot along itslower side for the passage of the screen into said casing as it is woundupon said roll, the casing being otherwise closed to protect the screenand roll from the weather.

To mount the roller ll within this casing l2, a bar It is pivotallymounted at its 'ends in openings in the end walls l3 of said casing andextends therein adjacent the upper side thereof, and rigidly secured tosaid bar adjacent each end wall of the casing, is a hanger or lateralarm H, in the free ends of which arms, the ends of the roll shaft aremounted in the usual manner of mounting such roll having a spring ofsprings l8 for rotating the roll to wind the screen thereon. The roll isthus mounted to swing away from the back wall M of the casing as thescreen is wound upon the roll and the .roll of screen increases indiameter, and to swing toward said wall as the screen is unwoundtherefrom, thus maintaining a straight run for the screen into and fromthe open upper ends of the guide channels 6 to prevent the screen frombeing sharply bent and from rubbing against the upper ends of the sidewalls of these channels or the lower edge of the front wall of thecasing. The necessity for a guide roll or roll for guiding the screen tothe spring roller is thus eliminated.

To hold the vertical side edges of the screen I within said channels 6when the screen is pulled down and held in that position against theaction of the spring l8, screw eyes H! are screwed nel and through theside edges of the screen, thus fixing the edges of the screen in saidchannels against being pulled therefrom, as by pressure against theinner or outer sides of the screen intermediate its ends; and to holdthe lower end of the screen or binding 9 thereon, within the lowerchannel member 8 secured to the window sill and thus hold the screenextended or pulled down, a hook 20 is secured to said binding to engagewith a suitable eye or other means on the sill or on said channelmember.

As shown in Fig. 3, the edge portion 01 the screen may be provided withan eye 2| for each screw l9 to pass therethrough and thus strengthen thescreen against tearing under pressure; and as shown in Figs. 4 and 5means may be provided for clamping the screen edges within the channels6, such clamping means being substituted for the screws l9 if founddesirable, such clamping means each comprising a single plate or strip22 within the channel having laterally bent ends 23 to project throughholes in one wall of the channel, and a screw 24 is'mounted in ascrew-threaded opening in said wall to engage at its inner end, saidplate intermediate the What I- claim is:

1. In a window screen comprising a screen strip, channel guide members01' open channel form and of U-shape in cross section to receive andguide the side edge portions of said screen strip; fastening meanssecured within said chan-. nels of said guide members against movementwith said screen and spaced at intervals along said channels to engagethe edge portions of said screen and secure the same therein againstlongitudinal movement and against being pulled from said guide channelsby lateral pressure upon said screen.

2. A window screen as characterized in claim 1 and wherein eachfastening means for holding the edge portions of said screen within saidchannels of said guide members, includes a member engaging an opening ina side wall of said channel and extends into said channel.

3. A window screen as characterized in claim 1 and wherein eachfastening means for holding the edge portions of said screen within saidchannels of said guide members comprises a clamping member mounted uponone side wall of each channel and held againstmovement with said screen,and a screw member passing through said wall to force said clampingmember laterally of said channel to clamp the edge portion of the screenbetween said member and the opposite wall of the channel.
